Description

Technical Field

[0001] The present invention relates to the field of coking technology, and in particular to a closed coke field stacking and reclaiming system and method. Background Art

[0002] At present, when distributing coke in a coking industry warehouse or a closed coke field, the distributing process selected is mostly point or line distributing. Due to the coke accumulation angle, the space volume within the effective utilization range cannot be achieved, resulting in low coke storage per unit area.

[0003] Although the coke field stacker-reclaimer can achieve surface stacking and reclaiming, it has the advantages of large effective utilization of space volume and high coke storage capacity per unit area. However, the existing closed operation workshops generally have large width spans and high top heights. In addition, the coke field stacker-reclaimer has a complex structure and is inconvenient to maintain. Especially for closed coke fields that use stackers but require relatively small coke reserves, there is still a disadvantage of high storage cost per ton of coke.

[0004] In order to increase the coke reserves per unit area, some coking plants install loaders in the coke field to assist in stacking and retrieving materials. The production automation level is low and the stacking and retrieving operation is labor-intensive. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a closed coke field stacking and unloading system and method. Surface stacking and unloading can be achieved inside the coke field, the space volume is effectively utilized, the coke storage capacity per unit area is high, and the storage cost per ton of coke is low.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A closed coke field stacking and reclaiming system comprises a stacking belt conveyor, a rack-type unloading vehicle, a bridge-type overhead crane coke placing machine, a semi-gantry scraper reclaimer and a reclaiming belt conveyor; the stacking belt conveyor is arranged on a composite foundation support platform in the X direction, and the rack-type unloading vehicle is arranged on the X-direction support track of the stacking belt conveyor; the bridge-type overhead crane coke placing machine is connected to the discharge port of the rack-type unloading vehicle, the bridge-type overhead crane coke placing machine is arranged between the composite foundation support platform and the single-row foundation support in the Y direction, the bridge-type overhead crane coke placing machine comprises a placing device and an overhead crane, the placing device is arranged on the Y-direction track on the overhead crane, and the overhead crane is arranged on the X-direction running track fixedly connected to the composite foundation support platform and the single-row foundation support; the semi-gantry scraper reclaimer is arranged on the X-direction track fixedly connected to the coke field ground and the composite foundation support platform in the Y direction, and the reclaiming belt conveyor is arranged on the coke field ground in the X direction and is located below the discharge port of the semi-gantry scraper reclaimer.

[0008] Furthermore, it also includes a mobile 3D automatic surveying and mapping device, which is suspended at the bottom of the surveying and mapping device running track. The surveying and mapping device running track is arranged in the Y direction and is fixed to the composite basic support platform and the top of the single-row basic support.

[0009] Furthermore, it also includes a mist shooter, which is fixedly connected to a mist shooter platform, and the mist shooter platform is fixedly connected to a composite basic support platform or a single-row basic support.

[0010] Furthermore, it also includes an inclined bottom surface, which is fixedly connected to the focal field floor.

[0011] Furthermore, it also includes a corbel, which is fixed to the composite basic support platform and the side of the single-row basic support, and the X-direction running track is fixed to the corbel.

[0012] Furthermore, the bridge-type overhead crane coke laying machine and the frame-type unloading vehicle are both provided with a vehicle-mounted dust collector.

[0013] A closed coke field stacking and reclaiming method is implemented based on the above stacking and reclaiming system, and specifically comprises the following steps:

[0014] 1) The coke is transported to the coke field through a stacking belt conveyor and unloaded into the distribution device of the bridge crane coke distribution machine by a rack-type unloading vehicle;

[0015] 2) The overhead crane coke placing machine's charging device moves along the Y-direction track on the overhead crane, that is, the coke charging port of the overhead crane coke placing machine moves along the Y-direction to realize Y-direction charging; the overhead crane of the overhead crane coke placing machine moves along the X-direction running track, that is, the coke charging port of the overhead crane coke placing machine moves along the X-direction to realize X-direction charging; after the X-direction and Y-direction charging, the charging is piled on the inner surface of the coke field, and a coke pile is formed on the inclined bottom surface;

[0016] 3) The semi-gantry scraper reclaimer scrapes the coke from the coke pile to the reclaiming belt conveyor;

[0017] 4) The coke is transported out by the reclaiming belt conveyor.

[0018] Furthermore, in the steps 1) and 2), both the bridge-type overhead crane coke placing machine and the frame-type unloading vehicle are provided with on-board dust collectors to perform sealed dust removal operations during the coke transfer and unloading.

[0019] Furthermore, in steps 2) and 3), the mobile 3D automatic mapping device moves along the mapping device travel track, maps the shape of the coke pile below during movement, and then combines the pile density of the coke to obtain the mass distribution of the coke at various positions in the coke field.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The coke of the present invention enters the coke field through a stacking belt conveyor, and then enters the bridge crane coke distribution device through a frame-type unloading car. The bridge crane coke distribution device moves in the coke field width (Y) direction through the coke distribution port, thereby realizing distribution in the coke field width (Y) direction. The bridge crane coke distribution device can also move in the coke field length (X) direction, thereby realizing distribution in the coke field length (X) direction, and finally realizing the bridge crane coke distribution device on the inner surface of the coke field. The coke on the inclined bottom surface can be scraped by a semi-door scraper reclaimer to the reclaiming belt conveyor for delivery, thereby realizing the automation of the reclaiming operation. The present invention has the advantages of large effectively utilized space volume and high coke storage capacity per unit area; the width span of the operating plant is small, the top height is moderate, and it has the advantages of low storage cost per ton of coke.

[0023] 2. The mobile 3D automatic mapping device of the present invention is hung at the bottom of the mapping device running track. The mobile 3D automatic mapping device maps the shape of the bottom stockpile during movement, and then automatically obtains the mass distribution at each position of the coke field in combination with the stockpile density of the coke. This provides support for the control system to decide whether the bridge crane coke distribution device and the semi-gantry scraper reclaimer can perform the stacking and reclaiming operation at the appropriate position, thus realizing the unmanned operation of the stacking and reclaiming.

[0024] 3. The bridge-type overhead crane coke placing device and the rack-type unloading vehicle of the present invention are equipped with a vehicle-mounted dust collector to achieve sealed dust removal during coke transfer and unloading; at the same time, the mist ejector on the mist ejector platform performs dry mist dust suppression operations, effectively curbing dust pollution in the production process, improving the production environment, and ensuring the health of operators.
